# SC-30(4) Misleading Information

> **Enhancement of:** SC-30

## High-Level Description

**Family:** System and Communications Protection (SC)
**Framework:** NIST SP 800-53 Rev 5

Employing misleading information is intended to confuse potential adversaries regarding the nature and extent of controls deployed by organizations. Thus, adversaries may employ incorrect and ineffective attack techniques. One technique for misleading adversaries is for organizations to place misleading information regarding the specific controls deployed in external systems that are known to be targeted by adversaries. Another technique is the use of deception nets that mimic actual aspects of organizational systems but use, for example, out-of-date software configurations.

## What to Check

- [ ] Verify SC-30(4) Misleading Information is documented in SSP
- [ ] Confirm control is operating effectively
- [ ] Review evidence of continuous monitoring for SC-30(4)
- [ ] Verify enhancement builds upon base control SC-30

## How to Test

### Step 1: Review Documentation

Examine the System Security Plan (SSP) and related artifacts for SC-30(4) implementation details. Verify the organization has documented how this control is satisfied.

### Step 2: Validate Implementation

```
# For cloud environments, use cloud-audit-mcp tools
# For on-premises, review system configurations directly

# Example: Check if account management policies exist
grep -r "account.management\|access.control" /etc/security/ 2>/dev/null
```

### Step 3: Test Operating Effectiveness

Verify the control is actively functioning, not just documented. Check logs, configurations, and operational evidence.

## Tools

| Tool            | Purpose                               | Usage                                |
| --------------- | ------------------------------------- | ------------------------------------ |
| cloud-audit-mcp | Check encryption and network controls | `cloud_audit_encryption`             |
| nmap            | Network scanning                      | `nmap -sV --script ssl-enum-ciphers` |

## Remediation Guide

### Control Statement

Employ realistic, but misleading information in [organization-defined] about its security state or posture.

### Implementation Guidance

Employing misleading information is intended to confuse potential adversaries regarding the nature and extent of controls deployed by organizations. Thus, adversaries may employ incorrect and ineffective attack techniques. One technique for misleading adversaries is for organizations to place misleading information regarding the specific controls deployed in external systems that are known to be targeted by adversaries.

| Finding                                         | Severity | Impact                                          |
| ----------------------------------------------- | -------- | ----------------------------------------------- |
| SC-30(4) Misleading Information not implemented | High     | System and Communications Protection            |
| SC-30(4) partially implemented                  | Medium   | Incomplete System and Communications Protection |
